1. Track Overview

Real-world background

• Location: Pevely, Missouri
• Nickname: “Pevely”
• Size/type: A high-banked 1/3-mile clay oval
• Notable events: Home of the World of Outlaws and the Ironman 55
• Character: A tight, elbows-up bullring where momentum, traffic management, and precision around the cushion separate the quick from the quick-and-wrecked. It’s short, fast, and punishes indecision.

Layout and banking

• Shape: Classic oval with short straights and tight corners
• Banking: Steep for a third-mile, which creates big corner speed and a heavy, building cushion
• Turns:
  • Turns 1–2: Typically a touch tighter, often favors a fine-tuned entry and a “cut-down” exit when slick
  • Turns 3–4: Slightly more sweeping; drivers can carry more entry speed and work multiple lanes

Unique characteristics

• Walls are close at corner exit, especially on the backstretch out of Turn 2
• Inside berm/tires can be used to anchor the bottom, but touching them will upset the car
• The cushion forms quickly and gets tall; riding it is fast but risky
• Mid-corner slick develops early, forcing either a disciplined bottom or a brave top

Typical racing lines and how they change

• Early session (moist/tacky): Bottom and low–middle are king; you can pinch turns and drive off hard
• As the track ages: The center polishes first; the bottom loses entry bite while the top shelf builds and becomes the fastest line if you can commit
• Late feature (slick): Split personality. The top cushion is often the outright speed line, while a well-executed “cut-down” or disciplined bottom can pass cars who make mistakes riding the wall

Surface evolution (iRacing specifics)

• Cushion build-up: Outside lane grows a chunky cushion against the wall; it gets faster until it becomes too sharp or sketchy
• Slick zones: Middle of both corners first, then the bottom entries; exits of 2 and 4 polish where throttle comes in
• Moisture levels: Pockets of dark, tacky dirt remain near the bottom on entry and sometimes very high on exit—scan for them lap by lap
• Rework sessions: If practice/qual heats reset moisture, be ready to adapt; preferred grooves change drastically from one session to the next

2. Key Things to Know About This Track

1) Exit of Turn 2 eats cars

• The backstretch wall arrives fast and closes in; cars drift up as they pick up throttle. Leave a margin or you’ll tag it.

2) Mid-corner slick shows up early

• The middle lane polishes off first. Don’t stubbornly drive through it; either rotate earlier and cut under, or go up to the cushion.

3) The cushion pays—but it bites

• It forms quickly in 1–2 and 3–4. Commit with confidence and keep the right-rear in it without climbing over. One mistake can send you to the fence.

4) The bottom is better than it looks (with discipline)

• Even when the bottom looks slow, there’s often small strips of moisture on entry/exit. If you can roll in low, rotate, and straighten early, you’ll surprise people blowing the cushion.

5) Entry timing matters more than brake pressure

• Over-slowing entry makes you a sitting duck. Aim to set the nose with a lift or a light brush of brake; then use throttle to finish rotation.

6) Rookie mistake: turning in too early

• Early turn-in puts you in the slick mid-corner and forces an ugly push to the wall. Wait the extra half-beat, square the car, and drive off straighter.

7) Setup tendency: slightly free on entry, planted off

• I-55 rewards a car that will rotate quickly on entry but still hook up off the corners as the track slicks. Too tight = dead in the center; too loose = snap on exit.

8) Gear for drive off, not just straightaway speed

• It’s a short track. Being a touch short on gear to launch out of the corners often beats hitting the limiter on the flagstand.

9) Wing management (sprints) is huge

• Run less angle/forward early when it’s tacky; move the wing back/add angle as it slicks to stabilize the rear. Adjust in small increments.

10) Slider lanes are alive and well

• Classic I-55 sliders into 1 and 3 work, but you must clear cleanly and leave room on exit. The crossed-over cutback is the standard counter.

3. Best Strategies for Fast Laps

Optimal entry points

• Turn 1:
  • Tacky/early: Enter just off the wall, arc to a late apex in the lower groove, let it float to mid on exit
  • Slick/feature: Either enter high to the cushion and let it ride, or enter just off the slick mid, rotate earlier, and cut down to exit low
• Turn 3:
  • Tacky/early: A little deeper entry; keep speed up and use banking to help rotation
  • Slick/feature: Commit high if the cushion is good; otherwise, a shallow entry and early rotation to a straighter exit works best

Ideal brake/throttle control

• Brakes: Use just enough to set the nose and transfer weight; avoid big stabs that lock the fronts and kill entry speed
• Throttle: Feed it in; snap-throttle on slick just spins the rears and drifts you to the wall. Think progressive squeeze as the car points downtrack

How to read grip levels

• Visual cues: Darker dirt = moist = grip. Polished, shiny areas are slick. A fluffy, tall edge near the wall indicates cushion
• Audio/FFB: Wheelspin and engine flare indicate too much throttle too early. A muted, planted tone and steady steering effort usually means you’re in moisture
• Car behavior: If it won’t rotate mid-corner, you’re either too tight or stuck in the slick—change your angle or line

Adjusting as the track slicks

• Move up sooner than others if you’re losing time middle/bottom
• If the cushion gets ragged, try the “ledge below” it; sometimes one car-width down is fastest
• Explore the cut-down earlier exit: enter a lane up, rotate mid, then drive down to the moisture at corner exit

Mid-corner rotation tips

• Sprint-style: Small initial lift to set the nose; quick but controlled pitch to angle the car; catch it with throttle. Keep the rear tires in a controlled arc—not a slide
• Fenders (late models/streets/mods): Use a light brush of brake on entry to load the RF, ease off as you unwind steering, then pick up throttle once the car is angled toward the exit

Exit strategies

• Goal: Straight tires, early throttle. The straighter the rear tires are on exit, the more drive you’ll create
• Turn 2 especially: Don’t chase the wall; if you’re drifting, lift briefly, re-point, then reapply throttle

4. Race Strategy & Situational Tips

How to race other cars here

• Respect space on entry and exit; the wall plus a building cushion means small overlaps can become big wrecks fast
• Anticipate stack-ups mid-corner where the groove slicks; keep a small buffer in case the car ahead bobbles

Passing zones and overtaking risks

• Primary pass zones: Dive/sliders into 1 and 3 when you’ve got a run
• Risk points: Misjudged slider speed or not clearing by exit will collect both cars. If you go, fully commit and keep it off the brake

Defensive lines

• When on the cushion: Enter a half-lane lower to deny slider angles, then float back up smoothly
• When on the bottom: Protect entry and get off straighter. If someone slides you, cross under and drive off beneath them

Heat race vs feature dynamics

• Heats: Tacky and fast. Start positions matter; grip allows aggression. Bottom-to-middle often quickest
• Feature: Track widens, cushion dominates, bottom requires finesse. Long-run consistency and wing/brake-bias adjustments are crucial

Adapting during long runs

• If cushion deteriorates: Drop a lane to find fresh dirt, or adopt a diamond/cut-down line
• If a restart follows a track reset (league/hosted): Revert to “tacky mindset” and move low early. The first lap or two can be decisive

5. Car-Specific Tips

360/410 Sprint Cars

• Entry: Minimize brake; lift to set the nose and use steering/throttle to pitch the car
• Wing management: Start with less angle/forward in moisture; slide back/add angle as it slicks to calm the rear
• Cushion: Keep the RR on it without climbing over. Small inputs are key; big sawing motions upset the car
• Sliders: Commit early with speed, aim to exit one lane off the wall to avoid pinching the leader into the fence

Pro Late Models / Super Late Models

• Throttle discipline: Roll in slowly; too much too soon creates wheelspin and lazy exits
• Brake bias: Slightly forward bias helps plant the RF on entry when slick; back it off if the rear gets nervous
• Lines: Cut-down works well in 1–2 when mid is slick. In 3–4, momentum on the top can be king—if it’s there, use it

Street Stocks

• Heavy and underpowered: Momentum is everything. Keep the car straight and avoid huge slides
• Bottom feeder: The low line holds moisture longer; be patient and drive off, don’t over-rotate
• Passing: Force mistakes by showing a nose high or low; capitalize when others over-drive the cushion

Dirt Modifieds

• Entry precision: These cars hate being yanked around; brake early, rotate once, and roll the center
• Throttle timing: Smooth pickup is essential; the front end must stay planted to keep steering authority
• Middle-lower arcs: On slick, a disciplined middle entry into a low exit can pass cushion runners who make errors

6. Setup Suggestions (General)

Note: No specific/illegal iRacing setups here—just general guidance.

Stagger

• Tacky/early: Moderate stagger to maintain stability under throttle; avoid over-rotation
• Slick/feature: Increase stagger slightly to help rotation in the center, but don’t go so far that the car becomes snappy on exit

Wing angle (sprints)

• Early moisture: Less angle/more forward keeps speed up and reduces push
• Slick: Add angle and move the wing back to plant the rear; adjust a click or two at a time as the groove fades

Shocks (general tendencies)

• Tacky: A bit more compression control to resist roll; keep the car on top of the track
• Slick: Soften where allowed to encourage compliance and grip; control LR rebound so the car doesn’t snap-loose on exit. Avoid overly stiff RF that induces push in the polished middle

Springs/bars (directional advice)

• If tight center: Slightly free up front (more RF bite/less LR hike hold), or add rear steer via setup options your car allows
• If loose on exit: Add rear stability (more wing angle in sprints, slight rear spring/shock adjustments, or move ballast/bias within legal ranges)

Gear selection

• Target: Off-corner acceleration without banging the limiter on the front stretch
• Tacky: Slightly taller gear may prevent wheelspin and keep you in the meat of the powerband
• Slick: Slightly shorter gear can help drive off, but beware excessive wheelspin; gearing that allows a clean, progressive throttle is best

Balance for slick vs tacky

• Tacky goal: Stability and drive—keep the car from bicycling as the cushion grows
• Slick goal: Free the car on entry/mid, stabilize on exit. Small adjustments beat dramatic changes
• In-car adjustments (where available): Sprint wing slider; brake bias in fenders; tiny changes between cautions can save your feature

7. Final Thoughts

Federated Auto Parts Raceway at I-55 is a quintessential iRacing dirt bullring: fast, technical, and unforgiving. The mid-lane slicks off quickly, the cushion builds tall, and the wall lurks on corner exit—especially out of Turn 2. To excel here, master three things:

• Entry timing and angle: Don’t turn in too early. Rotate where there’s grip.
• Throttle discipline: Squeeze, don’t stab. Straighten the car early for maximum drive.
• Lane evolution: Read the dirt. When the middle dies, commit to the cushion or execute cut-downs to the bottom.

Practice plan:

• Run short sessions starting tacky to learn the fast bottom line, then repeat on a worn track to practice cushion work
• Focus drills: 10-lap sets doing only low lines; then 10-lap sets only on the top. Finish with slider/crossover reps against AI
• Review replays from cockpit and chase cams to see how much you’re turning the wheel at apex and how straight your exits are

Get comfortable making small, timely adjustments—both in line choice and in-car settings where allowed. If you can be fast at I-55 while staying off the wall and out of trouble, you’ll have the tools to win on any bullring in iRacing’s dirt lineup.
